介电各向异性带壳颗粒复合体系中非线性光学特性研究

Nonlinear Optical Properties in a Nondilute Suspension of Coated Particles with Dielectric Anisotropy

从拉普拉斯方程出发,利用等效介电常数法,从理论上推导出稀释条件下介电各向异性带壳颗粒复合体系的有效三阶非线性光学极化率的一般表达式,讨论了复合体系的有效介电函数εe≡εe+Xe|■O|2中有效线性介电常数和有效三阶非线性光学极化率随界面结构参数和各向异性强度的变化。

From the Laplace equation, with the dielectric constant method, we deduced the case of non - dilution, the ef- fective linear particle composite system and effective third - order nonlinear dielectric susceptibility of the analytical expres- sion and discussed the structure of the interface parmneters and anisotropy changes in the relationship.
